amdSYM as selectable marker for laboratory, wild, and industrial Saccharomyces strains. (A) The laboratory strain CEN.PK113-7D, the industrial strains CBS1483, Scottish Ale and the wild Saccharomyces eubayanus CBS12357, and the generated strains IMK468, IMK470, IMK473, and IMK474 were grown on SM-Ac and SM media and incubated at 30 °C. The plates were read after 5 days. (B) PCR analysis to confirm correct integration of the gene disruption cassettes was carried out on CEN.PK113-7D, CBS1483, Scottish Ale, CBS12357, IMK468, IMK470, IMK473, and IMK474. Amplification of Sc.HXK1 locus in CEN.PK113-7D and CBS1483 generated fragments of 1837 bp (a, c), bigger fragments, 2836 bp (b, d) were obtained in the strains IMK468 and IMK470 due to the integration of amdSYM. Amplification of the loci Sc.ARO80 in Scottich Ale and Sb.ARO80 in CBS12357 generated fragments of 4208 bp (e) and 4002 bp (g), respectively. Confirmation of the deletion of Sc.ARO80 in IMK473 and Sb.ARO80 in IMK474 by PCR-generated fragments of 2992 bp (f) and 2895 bp (h), respectively. The products obtained were then subjected to agarose gel electrophoresis.
